Redefining the mobile experience for hundreds of thousands of utility customers


Exelon Corporation is a Fortune 100 energy company that generates and distributes over 35,000 megawatts of power to customers in 48 states, the District of Columbia (DC), and Canada. In keeping with the company’s commitment to customer experience innovation, they partnered with Mindgrub to launch native mobile applications for their BGE, ComEd, and PECO operating companies.

Informed by customer research and user testing data, the team designed self-service functionality and convenient payment processing features specifically for the mobile user.

The Opportunity

Industry research shows that customer loyalty increases by an average of 15% when a utility launches a mobile application. Those loyal customers have been found to be more likely to recommend their utility company, spend more, cost less to support, and have a higher lifetime value.

Our Approach

The complexity and scale of the mobile application project made it an ideal project for the agile methodology. Mindgrub’s fully agile team divided the project into two-week sprints and collected customer feedback monthly through user testing sessions of the in-progress application.

To maximize usability and accessibility, these sessions included customers from diverse demographic groups, including dozens of customers with disabilities. Each mobile application is secure by design and integrates seamlessly with the operating companies’ instances of Oracle Mobile Cloud Service (MCS).

Successful app experiences are rooted in customer feedback and take full advantage of native mobile functionality.

Results That Matter

Exelon’s mobile applications have been downloaded over half a million times and have earned a star rating 30% higher than the utility industry average. Since launching in 2018, call center volume has decreased and transaction completion rates in the app have increased significantly relative to those on web. The app has also been recognized for mobile excellence and innovation in utility customer experience by organizations such as E Source, Chartwell, and the Academy of Interactive and Visual Arts (AIVA).
